Brennan Pronunciation Language(s) English Language(s) Irish Derivation Ó Braonáin Ó Branáin or Mac Branáin Meaning 'moisture', 'drop' 'little raven' Region of origin Ireland
Brennan ()[ 1] is an Irish surname which is an anglicised form of two different Irish-language surnames: Ó Braonáin and Ó Branáin (or Mac Branáin ).[ 2] [ 3] [ 4] Historically, one source of the surname was the prominent clan Ua Braonáin (O'Brennan) of Uí Duach (Idough)[ 5] in Osraige who were a junior Dál Birn sept stemming from a younger son of Cerball mac Dúnlainge (d.888).[ 6] Recent surname evaluations highlighted the geographic consistency of this lineage in the barony of Idough.[ 7] [ 8] However, based on the ultimate authority of Dubhaltach Mac Fhirbhisigh they are out of Ui Dhuinn (O’Dunn)[ 9] and, therefore, an Uí Failghi tribe, not Osraige. While it is clearly apparent that O’Hart's pedigree is erroneous, it is suggested that Ó Cléirigh probably became confused while transcribing from Mac Fhirbhisigh.[ 10] This is echoed by the modern scholar, Bart Jaski.[ 11]
The Irish surname Ó Braonáin , means "descendant of Braonán ". The personal name Braonán is derived from a word which means "moisture", "drop". The Irish surname Ó Branáin , means "descendant of Branán ". The personal name Branán means "little raven".[ 12] Brennan is also a given name.
